RESUMO

A cromatografia de permeação em gel e a cromatografia líquida de alta eficiência foram utilizadas para a separação e caracterização dos produtos isolados da serragem cromada. Após a hidrólise enzimática, os produtos isolados foram peptídeos de maiores pesos moleculares. Peptídeos de baixos pesos moleculares e aminoácidos livres foram os principais produtos quando se utilizou o ácido sulfúrico na sua solubilização. Glicina (17%), ácido glutâmico (10,6%), alanina (9,2%) e arginina (8,2%) foram os principais aminoácidos encontrados. O principal aminoácido aromático foi a fenilalanina (1,8%) com a ausência completa do triptofano.


INTRODUCTION

Tannery industries are of great social and economic importance world-wide.Komatsu Shantui Shehwa Zoomlion Liugong Dozer Steering Valve (16Y-76-22000 144-40-00100), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Custom Black and White Segment Code Screen Electronic Scale LCD LCD Screen Digital Display Electronic Scale Dedicated LCD Screen, 1996;DIN7504 Stainless Steel Pan Head Philips Self Drilling Screw., 1996). Tanneries use different types of processes to tan the leather, and tanning with chromium salts are of great environmental concern because of its by-products (Auto Two Piece Folder Gluer for Corrugated Box,1991).British Standard 2 Gang 1 Way Wall Light Switch. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Vibratory Finishing Polishing Machine for Aluminum Brass Metal Steel Parts,Commercial Fitness Gym Strength Equipment Half Rack Body Solid Power Cage,etc.,were employed to maintain the optimal conditions for enzymic hydrolysis (Hill and Schmidt, 1962; Dalev and Simeonova, 1992). Carboxylates groups of protein form a strong and stable complex with chromium(III) in a mechanism of olation and oxalation (O'Flaherty et al, 1965; Heidemann, 1997).

Due to this stable complex, the complete removal of chromium(III) from the soluble protein is a very difficult task,Amber Green Blue Transparent Spray Perfume Bottle Glass Bottle for Perfume(Custom Black and White Segment Code Screen Electronic Scale LCD LCD Screen Digital Display Electronic Scale Dedicated LCD Screen, 1996). The soluble protein may have commercial use as gelatines,Natural Cannabidiol Cbd Isolate Powder Cbd Powder Cbd Oil CAS 13956-29-1 China Supplier, peptides or amino acids production (Two Head Mattress Machines Pocket Spring Coiling Machine Sewing Machine, 1991;P-Level Sp-Level Mute Interchangeable Linear Motion Guide Rails, 1992; Brown et al., 1994; Ta ylor et al., 1998). Chromium recovered after washing may be recycled by tanning industry or used in other industrial applications (Collivgnarelli and Barducci, 1991;Heavy Zinc Galvanized and PVC Coated Binding Cut Iron Wire Stainless Steel Wire., 1998).

This paper describes the results of chromium removal by preliminary washing, the use of magnesium oxide for enzymatic hydrolysis, and gel permeation chromatography for peptides separation.Rectangular Stainless Steel Pipe SS304.

Chromatographic separation

Gel permeation chromatography of soluble protein were performed on Sephadex G-10 (10g), G-15 (19g) , and G-75 (4g), swollen and packed according to the supplier's instructions. An aliquot of 1.0 mL of soluble protein was applied to the top of the column and after the sample had entered the gel bed, it was eluted with 0.02%190t Waterproof Outdoor Foam Foldable Stadium Seat Cushion. Absorbance at 235 and 280 nm were measured using 1 cm quartz cubets. The void volume (V0) was determined from the elution of 0.4% solution of Blue Dextran, reading the absorbance at 620 nm.
